If I do go through with this, and I'm strongly leaning toward it at this point, I'm not going to make a big deal about it. Its going to be very clear that I'm not trying to be a troublemaker or attention-getter. My guess of what will happen is my teacher will tell me to stand up, thinking I'm not paying attention or something. I'll just shake my head no at that point. If he comes over to me I'll quietly tell him I'm not doing the pledge anymore, as it violates what I believe in (freedom). If at this point he wants to make it a problem, he'll get a problem alright. If he tells me to go my administrator I'm not going anywhere. I can easily see getting in-school suspension at that point but I wonder whats going to happen if I keep staying sitting during the pledge. I'm not gonna worry about it.
You need to chill out and do it the right way. You need to ask for an exemption ahead of time.
